IIEASURING DISPEH-SING CA? Filed March 18, 1933 www5 Patented Sept. 4,1934 UNITED STATES PATENT OFFICE 4 Claims.

My invention relates to measuring and dispensing device for containerswhereby a measured amount of material may be removed from the container.My invention is applicable not only to the measuring of liquids but alsoto the measurement of powdered and granulated materials and the like.

It is the principal purpose of this invention to provide a device ofthis character in which the measuring chamber is provided with a.movable wall under the control of the operator so that the size of themeasuring chamber is readily adjusted to the desired quantity to bedispensed.

More particularly it is a purpose of my invention to provide a measuringand dispensing closure for bottles and the like which closure isprovided with a partition or stopper member insertible into the outletneck and a closure portion- ;for closing the outlet rA thus providing a;chamber between the partition member and the closure which chamber maybe varied by moving the partition member in or out with respect to theclosure member together with means for alternately filling the chamberfrom Within the container and discharging the chamber contents throughthe closure.

Other and more specific objects and advantages of the invention willappear as the description proceeds in connection with the accompanyingdrawing wherein the preferred form of the invention is shown. It is tobe understood however that the drawing and description are illustrativeonly and are not to be taken as limiting invention except in so far asit is limited by the prior art and the appended claims.

In.the drawing:

Fig. 1 is the section longitudinal through the neck of a bottle equippedwith my invention;

Fig. 2 is a. top plan view of the device shown in Fig. 1; y

Fig. 3 is a side View partly in section of a modied form of cap; and

Fig. 4 is a side view partly in section of a modied form of theinvention as applied to a large container.

Referring now in detail to the drawing I show at 5 a bottle having theneck portion 6 which is screw threaded at the top as indicated at 7 toreceive the cap 8. It is obvious of course that this manner of securinga cap on a bottle is conventional and the cap may of course be securedin any other suitable manner. This cap has the lip 9 thereon for pouringthe contents of the bottle and also has the outlet opening at 10 whichmay be of any suitable size. A valve 11 is pivoted in the cap 8 and iscut out as indicated at 12 so that in the position shown in Fig. 1, thecut out portion 12 and the outlet opening 10 register to permit thecontents in the neck of the bottle to be discharged. This valve member11 is normally held by means of the spring 13 in a position to close theopening 10 but may be moved by the hand piece 14 into the position shownin Fig. 1.

With the neck 6 I provide a. partition member l5 which is carried by thehollow shaft 16 that projects through the valve 1l and has a rathertight fit therewith. The partition member 15 can be adjusted lengthwise.of the neck 6 by sliding the shaft 16 in the Valve member 11 endwisewith respect to the cap. In this way the member 15 can be positioned atthe line 4 as shown in Fig. 1 or moved up to any one of the lines 1, 2or 3 as desired.

Member 15 is preferably constructed of rubber or other suitablesubstance not affected by the materials to be dispensed from the bottleand is so constructed as to have a substantial frictional engagement ofthe bottle neck. This member 15 is provided with suitable openings suchas 17 and 18 and these openings are normally closed by the valve 19.Valvev 19 is mounted on the stem 20 which passes up through the shaft 16and has the operating head 21 projecting from the upper end of theshaft. A spring 22 urges the valve 19 into closed position. This springhowever is sufficiently weak that by applying pressure'to the member 21,valve 19 may be unseated readily in order to ll the chamber between themember 15 and the cap 8 by inverting the bottle. When this chamber isfilled member 21 is released allowing valve 19 to close and then member14 can be operated to uncover the opening 10 and allow the contents ofthe chamber to be dispensed.

In Figure 3 I have shown the cap 8' as provided With a tubular extension23 instead of the spoon like portion 9 as such extensions are veryuseful in connection with giving medicines and dispensing other kinds ofliquid.

In Figure 4 a large container 24 has the dispensing device 25 connectedthereto through the valve 26. This dispensing device 25 consists of acontainer preferably made up of glass 27 closed by means of a cap 28 and29, the cap 29 having the valve 26 connected thereto and having anoutlet valve 30 at the bottom thereof.

The piston 31 is adjustable lengthwise in the cylinder 27 much in thesame fashion as the partition member 1 5 is in Fig. l. The stem 32 isused in adjusting this piston.

Operation oi the device in Figure 4 is as iollows:

In inoperative position the piston 31 is shoved off the end piece 29.Now when a quantity piece oi' fluid is to be dispensed valve 26 isopened, valve 30 being closed and piston 31 is pulled back the desiredamount to give the quantity to be dispensed. This draws the liquid intothe chamber and valve 26 is then closed. Valve 30 is opened and piston31 is shoved back against the end piece 29 thus adjusting all of theliquid after which the valve 30 may again be closed to leave the deviceready for the next dispensing operation.

From the above description it is believed that the construction of thisdevice will be clear to those skilled in this art. Having thus describedmy invention what I claim as new and desire to secure by Letters Patentis:

l. A measuring and dispensing closure device for containers such asbottles and the like having a partition member insertible a variabledistance in the container to isolate a portionof the space thereinadjacent the outlet from the remainder of the space therein, a closurefor the container outlet, valve means for said partition member topermit passage of the container contents therethrough, and valve meanscontrolling discharge through said closure.

2. A measuring and dispensing closure device for containers such asbottles and the like comprising a closure member for the outlet fromsaid container, said closure having a discharge opening therein, and avalve controlling said opening, a stem slidable through said closuremember and having thereon and movable within the container, apartitionmember for separating a variable portion of the interior ofsaid container adjacent the outlet from the remainder thereof to providea measuring chamber, and valve means onsaid partition member forcontrolling flow of material into said chamber. A

3. A measuring and dispensing closure device for containers such asbottles and the like comprising a closure member for the outlet fromsaid container, said closure having a discharge opening therein, and avalve controlling said opening, a stem slidable through said closuremember and having thereon and movable within the container, a partitionmember for separating a variable portion of the interior-of saidcontainer adjacent the outlet from the remainder thereof to provide ameasuring chamber, and valve means on said partition member forcontrolling ilow o1' material into said chamber, said valve means havingan operating member projecting outwardly through said stem.

4. A measuring and dispensing closure device for containers such asbottles and the like comprising a closure member for the outlet fromsaid. container, said closure having a discharge opening therein, and avalve controlling said opening, a stem slidable through said closuremember and having thereon and movable within the container, a partitionmember for separating a variable portion of the interior of saidycontainer adjacent the outlet from the remainder thereof to provide ameasuring chamber, and valve means on said partition member forcontrolling ow of material into said chamber, said valve means having anoperating member projecting outwardly through said stem. said operatingmember being slidable endwise in said stem, and spring means holdingsaid operating member in position to close the valve means.
